i had this built by my blacksmith friend,its a bit agricultural and heavy,but its very strong and not going to break the 1st time you use it.
it attaches where the bumpers fix,i used drillscrew things through the metal of the car and into the jig,the box section is the same size as the chassis so theres no room for it to move about,then you attach the lifting frame parts by sliding the shafts into the tube securing with a bolt.
you then use a bottle jack to raise the frame up to the required height,there are a few holes drilled in the legs which stay on the floor.
when you get to the last hole you can fit the bolts,tighten everything up,attach the handle then roll the car over,best have assistance if you are not sure,but it rolls easily but its a bit unerving tipping your pride and joy over.
when i 1st did it (1st pic) i had the engine/interior in and the rolling part of the frame was not correct,i had it altered to drop the center of gravity and removed the engine,after that you could turn it over with 1 hand!
it would roll fine with the engine in,i was removing it anyway.
once rolled theres a locking disc with holes and a piece of tube for putting a bolt through to lock it,i fitted ratchet straps also,for piece of mind.
could easily be modified for any car with a bit of thought and a welder.
my project has came to an end due to time so im selling everything off.
im asking less than what it cost to have built,i spent a day modifying it too,its a fair weight and size so im not responsible for arranging a courier.
price is £200,call me on 07834545251,thanks,lee
